# Dealing with namespaces in Nokogiri.
#
# First thing you must do is abandon what you're used to with Builder,
# namespaces aren't just attributes on an element, they uniquely identify
# what sort of element you are building and, as such, you are better off
# specifying them manually.
#
# The key here is accessing the Nokogiri::XML::Element being built with
# b.parent, then you can set the namespace (distinguished by an element
# with a prefix such as "soap12:Envelope") or add a default namespace
